Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Dotdigital
- Pricing is anchored on contact tiers, so inactive and unsubscribed contacts keep counting until you actively delete them and the bill grows with list decay rather than with sending.
- SMS, WhatsApp and chat are add-ons billed on top of the platform fee, so cross-channel programmes cost noticeably more than the headline quote suggests.
- The automation builder handles scheduled and behavioural triggers well but is not designed for high-frequency real-time orchestration, which is where growing teams outgrow it.
- Attribution reporting beyond opens, clicks and connected commerce revenue is thin without the additional analytics module.
- Automation logic is not portable, so migrating away means rebuilding programmes by hand after exporting contacts and data through the API.
Sailthru
- The product sits in a portfolio with several overlapping platforms under one owner, so roadmap investment is a portfolio decision rather than a product decision and is worth asking about in writing.
- Pricing counts stored profiles, so retained inactive readers keep costing money long after they stopped opening anything.
- On-site personalisation requires a developer to implement the JavaScript and maintain the content feed, which puts the highest-value feature behind engineering time.
- Zephyr is a proprietary templating language, so template maintenance skills are scarce compared with the Liquid syntax used by most competitors.
- It is built for high-cadence content and retail sending, and B2B lifecycle programmes with long sales cycles sit poorly on the model.

Answered from the vendors’ own pages
Dotdigital: Are unsubscribed contacts billed?
Yes, if they remain in the account. Contact tiers count stored contacts, so suppression lists still consume allowance until records are removed.
Sailthru: Who owns Sailthru now?
Marigold, formerly CM Group, which also owns Campaign Monitor, Emma, Selligent, Liveclicker and Cheetah Digital.
Dotdigital: Is it a real alternative to enterprise engagement platforms?
For scheduled and behavioural ecommerce and B2B programmes, yes. For real-time cross-channel orchestration at scale it is not competing in the same bracket.
Sailthru: Does that affect the roadmap?
It can. Overlapping products in one portfolio compete for investment, so ask which platform is the strategic one for your segment before signing multi-year.
Dotdigital: Where is contact data stored?
In the region contracted, with UK, EU, US and Australian hosting available, which is why it appears on European shortlists with residency requirements.
Sailthru: Is it worth it just for newsletters?
For personalised daily newsletters at publisher scale it remains one of the strongest options. For simple broadcast sending it is heavily over-specified.
